Protection against radiation and burns through :
▪
signs placed in the workp
lace warning about danger to eyes: a sign reading “Caution, do
not look into flames!” The workplace must be closed off as completely as possible so that
people in the vicinity are sufficiently protected. Unauthorized people must be kept away
from the welding area.
▪
the walls in the immediate vicinity of permanent welding areas should not have a light
colour or glossy finish, windows must be treated up to at least eye-level to protect against
light transfer or reflection, e.g. by applying a suitable layer of paint.
7 OPERATION
7.1
Preparation.
The earth clamp (2) must be connected to the work piece or to the ground the work piece is
standing on.
Caution :
▪
make sure there is direct contact with the work piece. Avoid painted or insulated surfaces.
▪
The welding cable is provided with a special clamp to hold the electrode.
▪
Always wear the protective cap, it protects you and allows looking at the weld.
7.2
Welding.
After making all proper connections you can proceed as follows:
▪
put the bare end of the welding electrode in the clamp (1) and connect the earth clamp (2)
to the work piece.
▪
Switch the welder on (4) and choose the welding current by turning the hand wheel (3),
depending on electrode Ø you will use.
▪
Hold the protective cap before your face and wrap the electrode over the work piece, like
lighting a match. This is the best way to light the bow. Test on a trial piece first to check
wither you have selected proper electrode/current.

Caution!
Do not tick against work piece; this could cause damage and hamper the lighting of
the bow. As soon as the bow lights, try to maintain the correct distance to the work piece
(corresponding to used electrode). The angle to your work piece should be 60-80°.
Caution!
Always use pliers to remove used electrodes or to replace your work piece. Always
remember that the electrode clamp (1) must be put aside on an insulated surface! The slag
must only be removed after cooling down. When a weld is continued after stopping, the slag
at the end of it should first be removed.
WARNING:Do not use the welding power source for pipe thawing.
Current range in different duty cycle.
160 A/10 %
115 A/20 %

7.3
Protection against overheating.
Your welder is equipped with an overheat protection. It protects the welding transformer for
overheating. When overheating occurs, the warning lamp (5) will light. Let your welder cool
down for a while.
